`Result::unwrap_or_default()` suggested for MSRV < 1.16

[samueltardieu]

Summary

Result::unwrap_or_default() should not be suggested if the MSRV is not at least 1.16.

Reproducer

I tried this code:

#[clippy::msrv = "1.15"]
fn f(foo: Result<Vec<u32>, &'static str>) -> Vec<u32> {
    foo.unwrap_or(vec![])
}

fn main() {
}

I expected to see this happen: no suggestion of Result::unwrap_or_default()

Instead, this happened:

5 |     foo.unwrap_or(vec![])
  |         ^^^^^^^^^^^^^^^^^ help: try: `unwrap_or_default()`
